VEHICLE-WHEEL'.

To all whom t may concern f Be it known that I, ALFRED SCOTT, a citizen of the United States, and a resident of.

Princeton, in the' county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Vehicle-Vheels, of which the following is' a full, clear, and

' exact description.

My invention relates to improvements in,

vehicle wheels, and it has for its object to provide one with a'fixed rim having recesses in its periphery in which plugs on a rim are normally disposed, the plugs being held normally against rotation relatively to the fixed rim by catch members which, at the will of the operator, may be moved out of the path of the plugs, so that the rim may rotate relatively to the fixed rim to a position where the plugs are disposed at the lateral openings in the fixed rim to permit of the removal of the rim from the fixed rim by moving the rim laterally relatively to the fixed rim.

Additional objects of the invention will appear in the following complete specification, in which the preferred form of the invention is disclosed.

IIn' the drawings similar characters of reference indicate corresponding parts in all the views, in which- Figure 1 is an elevational View, partially in section, of a wheel provided with my improvement, parts being broken away; Fig. 2 is a fragmentary sectional view, showing the outer rim having the plugs in position relatively to the inner Irhin or fixed rim to permit the plugs to pass through the lateral openings in the fixed rim; Fig. 3` is a sectional view on the line 3-3 of Fig.'1; and Fig. 4 is a fragmentary sectional View showing how the valve for the pneumatic tire mounted on the outer rim4 is dispose through one of the plugs.

By referring tothe drawings it will be seen that the wheel 5 has a hub 6 and spokes 7, which connect the hub 6 with the fixed rim 8. This fixed rim 8 has a pluralityof recesses 9 in its periphery, there being lateral openings 10 in the fixed rim 8, which extend to the recesses. A pneumatic tire 11 is secured to the outer rim 12 in any preferred manner, this outer rim 12 having plugs 13, which are adapted to enter the recesses 9 through the lateral openings 10 inthe fixed rim. `Vllienthcplugs 13 are dis- Y v Speccation of Letters Patent. ,l

-posed on the recesses9 it is. impossible to tothe fixed rim 8, and away from the lateral openings 1.0. In order to hold the outer rim 12 relatively to' the fixed rim 8 when the plugs 13l have been moved in the recesses 9 away from the lateral openings 10, I provide a catch device 14, which consists of a catch member 15 pivoted in a recess 9, this catch member 15 being provided for engaging an end of the plug 13 for holding the said plug against' one end of the. recess 9. There are openings 16 in the fixed rim 8 for receiving the clamping member 15 when it is moved out of the path of the plugs 13 to permit of the movement of the outer rim 12 relatively to the fixed rim 8, so that the plugs 13 may be disposed at the lateral recesses 10 to permit of the removal of the outer rim. A spring 17 presses yieldingly against the clamp member 15, for holding it in the recess 9, and this spring 17 is disposed around a stud 18, which'is secured to thecatch member 13, so that when the stud 18 is drawn inwardly it will carry with it the -catch member 15, out of the path ofthe plugs 13. This stud 18 is disposed through an orifice 19 in the fixed rim 8, which communicates with one of the openings 1G. The stud 18 is threaded kand meshing with the threads on the stud there is a nut 20.@ There is a wing member 22 having an orifice through which the stud 19 -is disposed, this wing member 22 engaging the sides of the nut 20, so that when the wing member 22 is rotated it will carry with it the said nut 20. The wing member 22 presses against a seat 21, which also has an orifice through which the stud 19 is disposed, this seat 21 resting against the inner side of the inner rim or fixed rim 8.

In the drawings I show two of the clamping vdevices v14e, but it will be understood that I maymake use of only one of the clamping devices, or should occasion require a num- -berof them may be employed. s y

InvFig. 4 of the drawings I show a valve 23, for the pneumatic tire 11, this valve 23 projecting in an opening 24, in one of the plugs 13. There is a threaded opening 25 in the fixed rim 8, which registers with the valve 23, when the plugs 13 travel in the recesses, so that one of them has passed a clamping device 14, and the outer rim is held thereby relatively to the xed rim. It will be seen that the plugs are tapered toward -move them with the outer rim 12 relatively u their ends 13, andthat the recesses 9 are similarly tapered at 9a, so that the plugs Will be wedged ,at the ends of the recesses to assist in holding the outer rim relatively to the fixed rim.` 4lVhen the Wheel-is driven ahead the ends 13a of theplugs arel driven against the ends 910i therecesses 9, andthere is no strain on'the catch members, but when the vehicle'. is backed the catch members serve to prevent the plugs 1.3 from traveling in the recesses 9,'and the outer rim, l2 is thereby prevented from moving relatively to the fixedrim 8.

4Having thus described my invention I claim as new anddesire to secure by Letters Patent: 'l i 1. In a Wheel a iiiii having arece'ss With an opening extending l.through the side ot' I the rim and a radially disposed orifice leading to the recess, asecond rim having a plug adaptedA to enter the recess through the opening and to move in therecessivhen the Asecond rim is rotated relatively to the first rim, a ,catch member pivoted at one 'end in the recess to engage the plug to limit the movement of the'plug in. the recess, a

.threaded stud'disposed in the orifice and secured to the other endofthe catch member I to move the catch member out of the path v of the plug,.a nut meshing with the thread on t-he stud, and aseat against which the nut lis' 'adaptefdfto' press.

4 v 2. In a Wheel a rim having a recess With 'an opening extending through the side of the iniand a radially disposed orifice lead- 'ingto the recess, a` second rim having a plug adapted to enter the recess through the opening and to move in the recess when the second rim is rotated relatively to the firstl rim, a catch member pivoted at one-end in the recess for engaging the plug to limit the movement ofthe plug in the recess, a threaded stud disposed inthe orifice and secured to the other end of the catch member to move the catch member out of the path of the plug, a spring on the stud for engaging the ii'st rim and the catch member for holding the catch member in the path of the plug, a nut meshing with the thread on the stud, and a seat against which the nut is adapted to press.
